Identification of respective components of women's hair care products (hair tonics, hair treatments, hair creams and waveset lotions) remaining on human hair was investigated. Women's hair care products (hair tonics of 15 brands of 6 manufacturers, hair treatments of 23 brands of 9 manufacturers, hair creams of 24 brands of 14 manufacturers and waveset lotions of 40 brands of 12 manufacturers) were identified by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) after extraction with ether. Among 102 brands of women's hair care products from 16 manufacturers, components of 66 brands remained on hair (hair tonics of 7 brands, hair treatments of 19 brands, hair creams of 24 brands and waveset lotions of 16 brands) were identified. It was notable that remaining components were detected in all of hair creams. Those of 66 brands were grouped into 27 classes on the basis of components, and among them 12 brands were identified by their characteristic peak (s) detected by GC and GC-MS. Only diethoxyethyl adipate in two brands and docosamethyldecasiloxane in one brand were common components of men's hair care products (hair liquid, hair tonic and hair rinse), and the rest of 63 brands were identified without interference in men's hair care products peaks on gas chromatograms and mass spectra. Major components of hair tonics were detected even 5 d after treatment, hair treatments were 20 d, hair creams were 10 d, and waveset lotions were detected even 5 d after treatments. From these results, if major components were detected from treated hair, the brands of women's hair care products (hair tonics, hair treatments, waveset lotions and hair creams) can be identified.
